15. Calculation Interface Contract (Handoff to RFC-036)

RFC-035 does not calculate concern posture. It defines the valid measurement substrate that RFC-036 may consume. This section specifies only the interface contract between the two — not the calculation semantics, which belong to RFC-036.

15.1 The Admissibility Precondition

A Concern Calculation Engine MUST treat every vector value as inadmissible unless the value carries evidence, provenance, measurement type, extraction method, uncertainty, and permitted operations.

Stated as a hard constraint on the consumer:

A concern calculation MUST NOT consume variables that are inadmissible, untyped, unsupported, or mathematically incompatible with the declared calculation method.

15.2 What RFC-035 Hands Off

RFC-035 produces a validated Mediation Vector. RFC-036 consumes it. The handoff carries:

{
  "mediation_vector": [ /* fully declared, validity-checked variables */ ],
  "gap_vector":       [ /* per-variable gaps via each variable's gap_operator */ ],
  "admissibility_map": { /* per-variable admissibility level achieved */ },
  "domain_of_concern": "autonomous_systems"
}

RFC-036 is responsible for: weighting, aggregation, hard-stop logic, posture classification, and observer routing. RFC-035 guarantees only that every variable handed off is valid, typed, provenance-bound, and gap-computed by a scale-appropriate operator.

15.3 Relationship to RFC-032 VERIFY

VERIFY (RFC-032) is a consumer of the measurement substrate, in the same role RFC-036 will formalize. RFC-032’s CODE grader is a specific, deterministic implementation of concern posture calculation — valid only where all variables use deterministic extraction and subtraction-valid scales. The general calculation semantics are deferred to RFC-036.

RFC-035 defines measurement validity. RFC-036 defines calculation semantics. The boundary is strict:

RFC-035 = measurement validity   (is this variable a defensible measurement?)
RFC-036 = calculation semantics  (how do valid measurements combine into posture?)
